Have you ever tried to love someone as hard as you could for five minutes? It sounds like a strange thing to attempt, but that's exactly what the people in a study at the Stanford Center for Cognitive and Neurobiological Imaging were asked to do while they sat in an fMRI machine. They scanned people of varying ages, and the person whose brain registered the most love "won." There was no prize, other than bragging rights, but in watching these poignant, fascinating interviews that Brent Hoff did with all the subjects, it becomes clear that they all found the experience unexpectedly moving and learned something about what it means to love and be loved.
